Torque limiters

A torque limiter is a safety coupling: it transmits torque up to a set value and, if the load exceeds it due to a jam, impact, or blockage, it slips or disengages to protect the motor, gearbox, chain, and machine. It is installed between the motor and the load, or inside a sprocket or pulley, and limits the force reaching the most sensitive transmission components.

Depending on how they operate, there are friction types, which slip and continue transmitting when the load drops, ball or detent types, which disengage and re-engage, and shear pin types, which break and are replaced. RINGSPANN codes, such as 2504-000001-A00002, 3502-010001-B240VW, and 4470-004800, are part numbers and are ordered complete. In TSUBAKI, the code includes the series and a number, such as TGM20, TGM200, TL10-C, and TL200-1C; the final letters indicate a variant, so they are not truncated.

Selection is based on the trip torque, which is set above the normal working torque and below what the protected components can withstand. Then verify the shaft diameter, speed, frequency of overloads, whether it must fully disengage or continue slipping, whether it resets automatically or manually, allowable misalignment, and available space for mounting. They are used in conveyors, mixers, mills, presses, pumps, and agricultural and packaging machinery.
